Littelfuse, the global leader in circuit protection, on December 13, 2017, introduced 16 series of Automotive Qualified TVS Diode Arrays that are Production Part Approval Process (PPAP) capable. They offer automakers and high-end industrial manufacturers the confidence of a known and reputable single origin flow from wafer creation through testing of the devices used in their products. These AEC-Q101 qualified devices offer a durable and compelling protection approach for current and emerging interfaces in the automotive ecosystem for data lines, charging lines, control lines, and drivetrain, as well as for communication ports, including antennas, against damage due to electrostatic discharges (ESDs), electrical fast transients (EFTs), and other overvoltage transients.

“These AEC-Q101 compliant TVS Diode Arrays give automakers and industrial manufacturers a wider choice of automotive qualified devices from which to choose,” said Tim Micun, business development manager, of Littelfuse. “They offer both uni-directional and bi-directional overvoltage protection solutions suitable for a broad variety of automotive electronics applications,” he further added.

• Part verification over a temperature range wider than that of commercial devices ensures known good, characterizable device performance.
• Defined product flow from front-end (wafer creation) through back-end (package, test, tape, and reel) processes gives OEMs assurance of wafer and package provenance, which is critical for inclusion in automotive and high-end industrial subsystems.
• Predictable pricing and component lifetimes through a partnership with raw materials suppliers’ support offering same site assembly projected out for multiple design-in cycles.
